CAR-COUPLING.

SPECIFICATION'forming part of Letters Patent No. 422,983, dated March 11, 1890. Application filed August V20, 1889. Serial 110.321,384. (No model.)

To all whom t may concern:

Be it known that I, ROBERT F. SILLIMAN, a resident of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Oar- Couplings; and I do hereby declare that the followingis a full,'clear, and exact description of the invention, th at will enable others skilled in the art to which it appertaihs to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several gures of the drawings.

My invention relates to improvementsin car-couplings and it consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims.

Figure' l of the drawings is a side elevation of myv improved coupling detached from the cars and coupled together as in use. Fig. 2 is an end elevation of one of the draw-heads detached. Fig. 3 is a central vertical longitudinal section of one of the draw -heads Figs. 4. and 5 are respectively a bottom plan and side elevation of the draw-bar detached. Fig. 6 is a bottom plan view of the springcontrolled latch detached. Fig. 7 is a similar view of the latch-controlling spring.

A A are the metallic draw-heads, preferably cast with a bellmouthed draw-bar chamber A. The chamber and its inclosing-walls are rectangular in cross-section. Projecting interiorlyfrom the two vertical Walls of thechamber are the two shelvesA, forming a slideway or platform for one end of the draw-bar. Directly beneath the bar-platform is a latch B, secured at one end to the draw-head by a socketyhinge B. The other end of the latch is controlled by the spring B2, secured to the head by the screws B3 and forced by the spring up against the lower side of the platform, as`

shown in Fig. 3. This end of the latch is also provided with an operating-handle B4. The draw-bar or coupling-link C is provided at each end with a hook C', having an inclined face C2, extending from the end of the hook to the end of the bar. It will be observed that the hooks are of less width than the bar and adaptedv to enter the space between the platform-shelves A2, while the bar occupies the upper portion of the chamber A between its lroof and the bar-platform, as shown by dotted lines Cin Figs. 2 and 3. Practically the drawbar so fills the chamber above its supportingplatform that when the draw-heads are uncoupled thel projecting draw-bar is held by its supporting-platform in substantially a horizontal position, in which position it is sure to enter the bell-shaped mouth of the drawhead to be coupled onto it. As it enters such a draw-head the inclined hook slides along the inclined spring-controlled latch and the bar along the bar-platform until the hook passes the end of the latch. Vhile the hook is passing over the latch the bar is forced by the latch and spring up against the roof of the chamber, being itself depressed to the bottom of the chamber to near the position shown by the dotted lines in Fig. 3. As soon as the hook passes beyond the end of the latch the latter is forced by the spring up against thelower sideof the platform, as shown by the solid lines in Fig. 3, and the hook falls down below the end of the latch, as shown by dotted lines C2 in the same ligure, where it is firmly held by the latch. The latch rests and turns in the socket B5, formed in the casting, which assists its pivot in resisting strains upon the draw-bar.

When it is desired to uncouple the drawheads, it is only necessary to force' the latch in one of the heads down into the bottom of the bar-chamber, as shown by dotted lines in Fig. 3, whereupon the draw-bar is free to pass from its chamber in that head. The latchoperating handle may have a ring B6 for convenience in operating the same. The latch may have a groove or slot B7, adapted to receive the barhook for the purpose of steadying the Abar in its chamber when the heads l IOO ends adapted to enter such chambers and-engage such latches, substantially as described, and for the purposes set forth.

2. In a car-coupling, the combination, with a draw-head having a longitudinal draW-bar chamber, of a draw-bar platform consisting of two shelves projecting interiorly from the vertical chamber-Walls, and a spring-controlled bar-latch located beneath suoli platform, substantially as described, and for the purposes set forth.

3. In a oar-coupling draw-head provided with a longitudinal draw-bar chamber, a drawbarsupporting vplatform consisting of tWo shelves projecting interiorly from the vertical chamber-Walls and. occupying the same horizontal plane Within the chamber, substantially as described, and for the purposes set forth. In testimony whereof I have hereunto set my hand this 13th day of August, 1889.
